MonoDevelop and Qyoto segfaults

linuxoidoz · January 29, 2010, 1:29pm

Hi,

I’m trying to figure out how to write Qt applications in C# in MonoDevelop. I have Qt-devel, MonoDevelop, Qyoto stuff installed. Plus I included all qt references I could find just to be sure. When I try a simple code


using Qyoto;

namespace QyotoTutorial
{
    public class HelloWorld
    {
        public static int Main(string] args){
            QApplication app = new QApplication(args);
            QPushButton button1 = new QPushButton("Hello World!");
            button1.Resize(100,30);
            button1.Show();
            return QApplication.Exec();
        }
    }
}

It gives me a lot of these errors:

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
=================================================================


The application was terminated by a signal: SIGABRT

Does anyone know what’s going on? Anyone tried this stuff? What am I missing?

Thank you.

Good progress - uninstalled Qt & Mono and reinstalled them and now it all works.

Does anyone know how to

either convert .ui GUI files made in Qt Creator to C# for re-use in MonoDevelop
or design GUI in MonoDevelop but use Qt (Qyoto) calls to GUI widgets

I’m guessing from the username that you’ve been asking on the KDE Bindings email list as well. For everyone else’s reference, here is the thread, which contains discussion and a link to my recent Using Qyoto tutorial that I wrote after first learning to use Qyoto in MonoDevelop.

The best way I found with .ui files is to set up a custom command on build that uses “uics” to compile the .cs files from them (my sample is in the tutorial).
